The 71991-419LF: Listed applications include automotive, general purpose, industrial, and telecommunications. The push-pull fastening type and bottom or top entry configuration allow flexible board placement in stacked PCB assemblies.
The 71991-419LF is a 38-position dual-row receptacle with all positions loaded. For exact pin numbering, refer to the product drawing.
The part number suffix 'LF' indicates lead-free and RoHS-compliant construction, consistent with Amphenol ICC (FCI) standard practice for this series.
The 'LF' suffix on 71991-419LF denotes lead-free / RoHS-compliant plating. The base number 71991-419 would be the non-RoHS version. All other specifications — 38 positions, 0.100" pitch, tin finish — are identical.
The current rating is not listed in the available specifications. For board-to-board connectors in this pitch class, typical per-contact current is in the 1–3 A range; confirm with the manufacturer's full datasheet for the exact derated value.
